- TITLE :Stripe Set with Parity Incorrectly Displays RECOVERED
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:
-
- --------------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT Advanced Server version 3.1
- --------------------------------------------------------------------------
-
- SYMPTOMS
- ========
-
- Upon restarting Windows NT Advance Server with fault tolerance, a striped
- set with parity is not recovered even though you regenerated it and
- received the message "Stripe set with parity #x [RECOVERED]."
-
- CAUSE
- =====
-
- When an NTFS fault tolerant stripe set with parity encounters discrepancies
- in redundant data (eg: by removing a disk drive), you can choose the
- Regenerate command from the Fault Tolerance menu even if there is not
- enough space (eg: a new disk) to regenerate the redundant data. After you
- choose the Regenerate command, the stripe set is shown as "Stripe set with
- parity #x [RECOVERED]," even though it has is not actually been
- regenerated. When you restart your computer, Disk Administrator correctly
- shows the strip set as [RECOVERABLE] again.
-
- This behavior can be reproduced with the following steps:
-
- 1. Set up a stripe set with parity.
- 2. Disable one drive in the set.
- 3. Start Disk Administrator.
- 4. Select the stripe set with parity; the status will be [RECOVERABLE].
- 5. From the Fault Tolerance menu, choose the Regenerate command.
- 6. Select the stripe set again, the status will be [RECOVERED].
- 7. Exit Disk Administrator, save changes, and restart your computer.
- 8. Disk Administrator shows the stripe set as [RECOVERABLE] again.
-
- STATUS
- ======
-
- Microsoft has confirmed this to be a problem in Windows NT and Windows NT
- Advanced Server version 3.1. We are researching this problem and will post
- new information here in the Microsoft Knowledge Base as it becomes
- available.
